摘要 快速公交系统（BRT）是缓解城市交通拥堵的高效交通方式。为了提高BRT的运行效率，以最小化出行时间为目标，提出了一种新的BRT时刻表优化模型，其中各公交站点的时刻表和沿线各路口的被动信号优先控制同时进行优化。制定混合整数非线性问题模型来捕获现实世界的操作约束。该模型采用非支配排序遗传算法求解。广泛的敏感性分析和案例研究结果验证了所提出模型的良好有效性。结果表明，当发车间隔大于360 s、交通量小于300 veh/h/ln、节点总数（包括公交车站和路口）小于60个时，可以获得15%以上的延误减少。
Abstract Bus Rapid Transit (BRT) is a highly effective traffic mode to relieve urban traffic congestion. To improve the operational efficiency of the BRT, a new schedule optimization model for BRT is proposed by using minimizing the travel time as the objective, in which the schedule at each bus stop and the passive signal priority control at each intersection along the line are optimized simultaneously. A mixed-integer nonlinear problem model is formulated to capture real-world operational constraints. The model is solved by the nondominated sorting genetic algorithm. Extensive sensitivity analysis and case study results validate the promising effectiveness of the proposed model. The results show that more than 15% delay reduction can be obtained when the departure interval is more than 360 s, the traffic volume is less than 300 veh/h/ln, and the total number of nodes (including bus stations and intersections) is less than 60.
